At the age of 16 in December 2013, Mor was on a trial training with Saint-Étienne but did not receive a contract.[5]
Mor played at Lyngby on U17 and U19 levels before he was released by the club in January 2015.[6] The message from the club was that "the conclusion is that the talent can not be redeemed in Lyngby Boldklub".[6] In 2016, it was reported that he was released due to attitude problems.[7]
FC Nordsjælland
On 31 January 2015, it was confirmed, that Mor had signed a contract with FC Nordsjælland,[8] despite being courted by other clubs in the Superliga and abroad. The original intent was for Mor to play for the U19.
Mor got his official debut for FCN on 28 November 2015.[9] Mor started on the bench, but replaced Guðmundur Þórarinsson in the 84th minute in a 0–1 defeat against Randers FC in the Danish Superliga. In the next league match after his debut, Mor was in the starting lineup against Brøndby IF.[10] Mor's performance earned him a new contract and a promotion to the first team squad from January 2016.[11]
Borussia Dortmund
Borussia Dortmund confirmed signing Mor on 7 June 2016,[12] announcing a five-year contract.[13]
In a training session after a defeat against Bayern Munich in April 2017, Mor and his teammates were sent on a run by manager Thomas Tuchel and physical trainer Rainer Schrey. When Tuchel and Schrey instructed Mor to continue on for an extra round, Mor reportedly loudly protested, which prompted a fiery reaction from Tuchel. Earlier on the year, it was also reported that Dortmund were dissatisfied with Mor's attitude and willingness to integrate into the team.[14]
He made only 12 appearances in the Bundesliga and UEFA Champions League for Borussia Dortmund during the 2016–17 season, usually as a substitute on the right wing or in attacking midfield.
Celta Vigo
On 29 August 2017, Mor signed for Spanish club Celta Vigo for €13 million.[15] That made him the second most expensive signing in Celta's history.
He started just only one Liga game for the club and played only 384 minutes until mid December. On 17 December 2017, he was on the bench again for the loss against Villarreal while youth team player Brais Méndez filled in for the suspended Iago Aspas.
"Emre has to understand that technical skill is not enough to earn him more playing time. There are no miracles or coincidences. Mentally, he needs to change."
—Celta coach Juan Carlos Unzué explaining the lack of playing time being handed to Mor.[16]
In April 2018, Mor was late for training before a home game against Sevilla after he had been excluded from the squad in two games. Unzué once again claimed, that Mor had to change his attitude before he again would be a part of the team. Mor then went out and apologized on Twitter, writing:
Good luck to my teammates against Sevilla. Disappointed I can't help them on the pitch today but I can only blame myself. As a professional I shouldn't have been late for training. This won't ever happen again and I will try everything to get back into the squad![17]
Afterwards, Mor was sent to train on his own for a period. Less than one month later, in May 2018, Mor was sent home early from training for the second time in a month.[18] Mor wasn't a part of the playing team for the remainder of the season.
The 2018/19 season started as the last season ended. In the first eight league games, Mor only played 38 minutes, despite Miguel Cardoso being appointed as the club's new manager. In January 2019, Mor was once again excluded from training because of his attitude and for acts of indiscipline.[19] He was left out from the squad in the following eight league games and was excluded from the training in over one month. Celta gave the player one more chance at the end of February 2019, where he returned to first team training.[20]
Galatasaray (loan)
On 31 July 2019, Galatasaray announced via social media that Mor had joined the club on a season-long loan.[21]
Olympiacos (loan)
On 31 January 2020, Olympiacos confirmed the signing of Mor, on loan from Celta Vigo for the remainder of the 2019–20 season.[22][23] Olympiacos would pay Celta Vigo a loan fee of €410,000 and Galatasaray would cover €290,000 from the contract. Celta Vigo had announced that the deal provided for a compulsory purchase by Olympiacos at the end of the 2019–20 season if specific player goals were met, as agreed between the two clubs, indicated that the compulsory purchase option was set at €4,000,000 and this amount would be paid by the Greek side Mor plays at least half of Olympiacos' matches before the end of the season, with a future resale rate for the Spanish club between 10% and 20%.[24]
On 2 July 2022, Mor joined Fenerbahçe on a permanent transfer, signing a three-year contract.[27]
Return to Fatih Karagümrük (loan)
On 1 January 2024, Fenerbahçe announced that Mor signed a contract with his old club Fatih Karagümrük for the latter half of the 2023-24 Süper Lig season with no option to make the move permanent.
Mor made his senior debut for Turkey against Montenegro in Antalya in May 2016. He was included in the Turkey senior team's squad for UEFA Euro 2016, making him the third-youngest player at the tournament.[30][31] He came off the bench to replace Cenk Tosun in Turkey's opening Euro 2016 game against Croatia. He was also part of the starting 11 in the last match Turkey played in the 2016 European Championship against the Czech Republic and made an assist to Burak Yılmaz for the opening goal.
